Ressler, 22811 Brookdale,Farmington, Mich. Filed Nov. 17, 1958, Ser. No. 774,508 2 Claims. (Cl.210-164) My invention relates to the construction of catch basins andsimilar structures and more particularly to catch basin constructionembodying a multiple section frame structure for the grate supportportion of catch basins in roadways having multiple superimposed layersof paving.

In the paving and maintenance of roadways, the process of adapting andinstalling catch basins, the upper edge of which is required to besubstantially flush with the top paving surface, consumes considerabletime and represents a material factor in the cost of paving andrepaving.

In particular, the cistern portion of the catch basin, generallyconstructed of brick or cement, is first installed or, it installed, theupper end must be built up to a predetermined height. A top frame, whichsupports the grate, is then installed in place on the cistern, the frameextending upward with the top edge substantially at the level at whichwill be the final surface of the pavement. The paving work is thenbegun, and in the case of multiple layer paving, such as a basic cementfoundation with an overlayer of asphalt, the first layers will befinished oif to a level below the top edge of the aforesaid frame,necessitating extra hand work.

Perhaps a more diflicult process is required where, in maintenance ofthe roadway, a new layer of paving is required to be laid over the oldpaving. The existing frame must be first removed by excavating, the toplevel of the cistern extended with additional masonry or brickwork, theframe replaced, and the excavation refilled, including the replacementof the lower pavement layers.

An object of the present invention is to eliminate costly catch basinwork in roadway construction by providing a multiple section framestructure.

Another object of the invention is to decrease difficulties of paving byproviding a catch basin construction with a multiple section upper framestructure such that each layer of paving may be laid flush with the topedge of a frame section.

A further object of the invention is to facilitate superimposing a layerof pavement over an existing roadway by providing a convenient multiplesection catch basin frame structure for readily raising the top of thecatch basin the required distance.

For a more complete understanding of the invention, reference may be hadto the accompanying drawings illustrating a preferred embodiment of theinvention in which like reference characters refer to like partsthroughout the several views and in which FIG. 1 is a perspectiveexploded view of the catch basin top frame structures including thegrate.

FIG. 2 is a cross-sectional view of a roadway portion illustrating partof the cistern and the frame structure partially in section.

FIG. 3 is a fragmentary perspective view looking up at one corner of theupper structure of FIG. 1.

FIG. 4 is a top plan view of the lower frame structure of FIG. 1.

FIG. 5 is a top plan view of the upper frame structure of FIG. 1.

FIG. 6 is a fragmentary cross-sectional view of the upper framestructure as taken substantially on the line 6-6 of FIG. 5.

FIG. 2 illustrates the present invention as it is used when a layer ofpaving is to be superimposed over an existing roadway, said roadwayoverlaying, for example, a bed of sand or gravel 10 and comprising alayer of concrete 11 and a superimposed layer of asphalt 12. The

"ice

new layer of asphalt is shown by the reference character 13.

The catch basin construction 14 preferably comprises a cistern structure15 built of brick or other building material, on top of which rests alower frame structure 16. An upper frame structure 17 is carried by thelower frame structure 16 and in turn supports a grate 18. Asillustrated, the top surface of the existing roadway, the asphalt layer12, has been formed substantially flush with the upper edge of the lowerframe structure 16. Instead of excavating to remove the lower framestructure 16 and build up the top of the cistern 15, preparation for thenew layer of asphalt 13 is accomplished by removing the grate 18 whichpreviously would have been carried by the lower frame structure 16,inserting the upper frame structure 17, laying the asphalt 13substantially flush with the top edge of the upper frame structure 17,and replacing the grate in the upper frame structure 17.

It will be apparent that in constructing a new roadway, the lower layerof concrete could be laid flush with the top edge of the lower framestructure 16, then the upper frame structure 17 can be installed and thefinish asphalt surfacing can be laid flush with the upper edge of theupper frame structure 17, thus facilitating paving operations andeliminating handwork.

The lower frame structure 16 is illustrated in FIGS. 1, 2 and 4 ascomprising a flat base member 25 which provides a broad supporting baseon top of the cistern 15, and a peripheral vertical wall 26 secured toor integrally cast with the base member 25 and having a peripheral topedge 27 to which a layer of paving will be laid flush. Inside the wall16 are secured or formed blocks 28 or other suitable support elements,each having its top surface depressed below the top edge 27 of the wall26 a distance substantially equal to the thickness of the grate 18, thusenabling the grate to be removably supported by the lower framestructure for use without the other frame structure 17 in roadwayslacking the top layer of paving 13.

The upper frame structure 17 is illustrated in FIGS. 1, 2, 3, S and 6 ascomprising a lower peripheral wall portion 30 dimensioned to fit withinthe lower frame structure wall 26, and an upper peripheral wall portion31 dimensioned to be substantially similar to the portion of the lowerframe structure wall 26 which extends above the support elements 28.Thus the upper wall portion 31 is laterally outwardly offset from thelower wall portion 30, providing for an inside peripheral upward-facingledge 32 and an outside peripheral downward-facing shoulder 33. Theshoulder 33 rests on the top edge 27 of the lower frame structure wall26. Support pads 34 are provided preferably at the four corners of theinside ledge 32.

The grate 18 is conventional, being dimensioned to selectively fitwithin the upper frame structure upper wall portion 31 or the upperportion of the lower frame structure wall 26, supported respectively onthe pads 34 or the support elements 28, its top surface beingsubstantially flush respectively with the top edge of the upper framestructure upper wall portion 31 or the top edge 27 of the lower framestructure wall 26.

The lower wall portion 30 of the upper frame structure preferablyextends below the top of the support elements 28 when positioned in thelower frame structure wall 26 and is provided with a plurality ofdownward facing recessm having shoulders 35 which may be adapted to reston the top of the support elements 28 for further supporting the upperframe structure 17 on the lower frame structure 16. Preferably the upperframe structure 17 is supported only by the shoulder 33 resting on theedge 27 of the lower frame structure.

Although I have described only one preferred embodi- 3 ment of myinvention, it will be apparent to one skilled in the art to which theinvention pertains that various changes and modifications may be madetherein without departing from the spirit of the invention or the scopeof the appended claims.
